This is because, in order to remove the needle plate, the lock only has to be opened against the force of the spring load. Tightening of the needle plate takes place automatically via the spring loading of the clamping lock, whereby, by appropriate selection of the spring preload, the required clamping force can be easily applied via the clamping lock. The load spring of the lock does not result in a significant increase in the mass that is moved together with the needle beam. The actuating gear causing the opening of the lock is attached to the cradle or scraper, but not to the needle beam, so that the expansion of the mass that can be moved through the needle beam is limited only by the lock. There is.

造によつて簡単に加えられ得る。[0006] The structural configuration of a lock can vary widely. This is because only the tightening of the needle plate in the needle beam by the spring load is important. If the lock has a spring-loaded tension hook which is movably guided in the direction of tension on the opposite side of the needle beam from the needle plate and perpendicular to the plane of the needle plate in the direction of tension. , particularly advantageous structural conditions are obtained. By supporting the tension hook on the side of the needle beam opposite the needle plate, the available space is advantageously utilized without impairing the function of the needle plate. Via the tension hook, the desired clamping force can also be applied in a simple manner with a relatively simple construction.

No restrictions arise regarding the needle distribution. in this case,
The release of the needle plate rim by the pull hook when opening the lock is due to the fact that the displacement guide for the pull hook is inclined towards the needle beam about an axis parallel to the needle plate rim. It is encouraged. This inclination of the travel guide is accompanied by a movement component that forces the tension hook laterally on the edge of the needle plate when the lock is opened, which, due to the associated lateral play, causes the needle plate to move after the lock is opened. make handling easier. A tension hook covering the edge of the needle plate serves as a guide device for the needle plate when it is to be pulled out of the needle beam parallel to the edge. In order to achieve an easy and compact tightening lock structure,
The displacement guide for the tension hook can consist of guide pins passing through the load spring and these guide pins can be screwed into the needle beam.

。In order to open the lock, the operating transmission must adjust the spring-loaded locking element in the opening direction against the force of the load spring. For this purpose, the operating transmission can have its own drive. However, it is also possible to design the operating transmission for the clamping lock as a locking stop on an adjustable scraper. This is because in this case the adjusting drive for the scraper can be drawn towards the clamping lock for adjusting the engagement stop. This construction is particularly recommended when arranging edge locks in the vicinity of structural parts fixed to the scraping strip. In the case of a movement guide of the clamping element of a clamping lock that is inclined to the direction of adjustment movement of the scraping strip,
During the opening movement of the lock, a relative movement between the engagement stop on the scraped side and the tightening element takes place. In order to avoid sliding friction during such relative movements, the engagement stops can each have a run-up roller for the tightening lock.

の切込みに係合する締め付け位置に戻る。Instead of a tensioning hook on the edge side, a tensioning hook located inside the needle plate face can also be used. In such a tension hook arrangement, the tension hooks can pass through the needle beam and engage through bolts connected to the needle plate, and these through bolts have notches for the hook bases. , for the tensioning hook which can be expanded by this cut, a landing surface is provided for expansion of the tensioning hook during the movement of the hook in the opening direction. The tensioning hook, which engages in the notch of the through bolt, tensions the needle plate against the needle beam under spring load, so that a fixed connection is created between the needle beam and the needle plate. However, in order to remove the needle plate from the needle beam, the through bolt must be released from the tension hook, which requires expansion of the tension hook from the notch. Since it is necessary to move the through bolt against the force of the load spring in order to release the lock, this movement of the through bolt is
Induction of expansion movements when, in the direction of movement of the tension hooks, landing surfaces fixed to the needle beams connect to these tension hooks along which these tension hooks slide under the desired expansion movement. It can also be used for. Therefore, the needle plate can be passed through the needle plate and removed from the needle beam together with the bolt without being hindered at right angles to the plane of the needle plate. To tighten the needle plate, the tension hook, upon release by the actuating gear, returns along the running surface to the tightening position in which it engages in the notch of the through bolt.

ような，別個の心合わせピンなどは不必要である。[0010] A tension hook arranged inside the needle plate surface defines a needle plate through bolt which passes through the needle beam, the needle distribution being possibly impaired by the through bolt. To reduce this possibility of damage, the number of through bolts must be limited. In order to be able to transmit the required clamping force despite this limitation of the number of threaded bolts, the tension hook can be formed by a tongue that occurs between the axial slots of the tube, in which case the needle The through-bolts of the plate each engage in a tube forming a tension hook, so that cooperation of one through-bolt and several tension hooks is ensured in a very compact construction. The tube tongue, which is configured as a tension hook, also has a sufficient radial spring action, which makes it possible to expand the tension hook by means of a through bolt. The landing surface which causes the tension hook to expand can in this case simply be formed by the outer cone of the guide sleeve of the needle beam for the through bolt. This guidance of the through-bolt in the guide sleeve also allows for the centering of the needle plate, so that separate centering pins or the like, as would be necessary, for example, in edge locks, are not required.

からである。The overall height of the lock can be reduced if a tube with a tension hook passes through a load spring which is supported on a flange attached to this tube. The spacing between these locks and the edge of the needle plate makes it difficult to operate the locks via the scraped one-sided operating transmission. For this reason,
In such an arrangement, it is advisable to configure the operating transmission for the clamping lock as push rods supported on a frame, which are actuated via a suitable drive and thereby actuate the clamping lock. It can be opened against the force of the load spring. The additional mass of these push rods is not significant for the needle plate drive. This is because these operating transmission devices are not attached to the needle beam but to the machine frame.

得る。The embodiment according to FIG. 3 shows an alternative construction of spring-loaded locks 3, but these locks also have a tension hook 10. That is, these tension hooks 10 cover the edge of the needle plate on the outside and are movably supported on a guide pin 23 screwed into the needle beam 2 on the side of the needle beam opposite to the needle plate 1. This guide pin passes through the load spring 19. This guide pin extends obliquely towards the needle beam 2 about an axis parallel to the edge of the needle plate, so that the needle plate 1 has a lateral play when adjusting the opening of the tension hook 10. is released so that the needle plate can be pulled out under the needle beam parallel to the edge, although it remains resting on the tension hook 10.

ルビーム２の方へ引つ張るからである。The actuating gear 4 provided for opening the lock 3 is, according to FIG. has been done. As can be seen from the right half of FIG. 3, when the scraping piece 7 is displaced downward in the upper reversal position of the needle beam 2, the engagement stop 24, which has a run-up roller 25 to avoid sliding friction, The tension hook 10 is pressed, and this tension hook is moved in the opening direction against the force of the load spring 19.
At this time, the needle plate 1 is released. After fitting the new needle plate 1, automatic tightening of the needle plate takes place by returning the scraping piece 7 to its starting position as shown on the left side of FIG. This is because the tensioning hook 10 tensions the needle plate towards the needle beam 2 by being loaded by the load spring 19.

からであり，それは検出器により検出され得る。[0019] The replacement of the needle plate can therefore be carried out very quickly and automatically, regardless of the construction of the lock, without any special operating costs. The spring-loaded tension hook also allows easy monitoring of the tightening of the needle plate. This is because tension hooks that do not engage the needle plate or the through bolt are moved beyond the tightening position by the load spring, which can be detected by the detector.
